Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to a telephone capable of making a telephone call without taking a handset.

(Prior art) A telephone converts a caller's voice into an electric signal, transmits the electric signal to the other party through a telephone line, and reproduces the electric signal sent from the caller through the telephone line into a voice for talking. And a function of transmitting a signal for selecting and connecting a desired subscriber from a large number of subscribers and calling the subscriber.

In recent years, demands for such telephones have been diversifying and becoming more sophisticated, so that it has become necessary to enhance the functions.

As an example of the enhancement of such a function, for example, Japanese Patent Application Laid-Open No. 61-202550 discloses a method in which a specific voice is detected in advance and stored as voice data. There is disclosed a hands-free telephone which automatically enters a hands-free state by inputting via a handset and eliminates the need to lift the handset.

Japanese Patent Application Laid-Open No. 60-1960, 60-54555 discloses that even when a telephone call is in progress using a handset, a voice for switching is input from a transmitting unit of the handset, and the handset is provided in the handset. A hands-free telephone has been disclosed in which a voice recognition circuit recognizes the voice, thereby saving the trouble of switching between a handset call and a hands-free call.

However, with a hands-free telephone that switches between a handset call and a hands-free call when an incoming call arrives, if a specific sound is input at the same time as a sound such as a bell that indicates an incoming call, that sound will be mistaken as sound. In such a case, the switching between the handset call and the hands-free call cannot be reliably performed.

(Problems to be Solved by the Invention) As described above, in the above-mentioned conventional telephone set that switches between a handset call and a hands-free call at the time of an incoming call, there is a possibility that the sound of a bell or the like indicating the incoming call is erroneously recognized as voice. In such a case, switching between the handset call and the hands-free call cannot be reliably performed.

The present invention has been made in view of such circumstances, and has as its object to provide a telephone capable of easily and reliably switching between a handset call and a hands-free call.

[Configuration of the Invention] (Means for Solving the Problems) In order to achieve the above object, a telephone according to the present invention comprises: a conversion unit for converting an input voice into an electric signal; In the case where an incoming call is detected by the incoming call detecting means, an incoming call notifying means for notifying that an incoming call is made with a notification sound that repeats a sound state and a silent state, and when a predetermined time elapses after the incoming call notifying means detects the incoming call. An incoming call notification switching means for switching the incoming call form of the incoming call notifying means so that the time of the silent state of the notification sound is longer than the time of the sounding state; and when the notification of the incoming call notifying means is a silent state, the conversion is performed. The apparatus comprises a voice recognition means for recognizing voice which is electrically converted by the means, and a control means for controlling various functions based on a voice recognition result of the voice recognition means.

Further, the incoming call notifying means notifies that there is an incoming call by a notification sound which repeats a sound state and a silent state intermittently and alternately.

Further, the control means has a function of switching to a hands-free communication state when the result of recognition by the voice recognition means is a voice to respond to an incoming call.

(Operation) In the telephone of the present invention, when the incoming call detecting means detects a call signal from the caller, the incoming call notifying means intermittently notifies the incoming call.

Then, when the notification state by the incoming call notification means is a silent state, the voice recognition means recognizes the voice signal converted into the electric signal by the conversion means, and based on the recognition result, the handset call or the hands-free call is switched. Will be

Therefore, since the voice recognition means can capture and recognize only the predetermined voice, erroneous recognition of the predetermined voice can be prevented.

(Example) Hereinafter, details of an example of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of a telephone according to the present invention.

As shown in the figure, the telephone includes a call detection unit 1, a call notification unit 2, a microphone 3, a voice recognition unit 4, a handset 5, a speaker 6, a changeover switch unit 7, and a call notification control unit 8. Have been.

The incoming call detection unit 1 detects a call signal from a caller.

The incoming call notification unit 2 intermittently notifies that there is a call from the caller, such as a bell, for example.

The voice recognition unit 4 has a standard pattern of voice commands registered in advance, and recognizes the voice by performing a similarity calculation between the standard pattern and the voice obtained via the microphone 3.

The handset 5 has a transmitting unit 5a and a receiving unit 5b.

The loudspeaker 6 is fixedly mounted on the side surface of a housing (not shown) together with the microphone 3 and converts an electric signal from a sender into a voice or the like.

The changeover switch unit 7 switches between a handset call using the handset 5 or a hands-free call using the microphone 3 and the speaker 6 based on the recognition result of the voice recognition unit 4.

The call notification control unit 8 controls the notification operation of the call notification unit 2, the voice recognition operation of the voice recognition unit 4, the switching operation of the changeover switch, and the like.

Next, the operation of the telephone having such a configuration will be described with reference to FIGS.

The voice command at the time of switching to the hands-free call described below is set to “high”.

First, in a normal state, the handset 5 is in a handset talking state (step 201).

In this state, the incoming call detection unit 1 constantly detects the presence or absence of a call signal from the caller (step 202). When the incoming call detecting section 1 detects a call signal, the incoming call notification control section 8 sets the bell sound and the silent section shown in FIG.
Output a continuous ringing tone (A) every second (step
203).

Thereby, the incoming call notification unit 2 notifies the receiver that the call has been made.

At this time, the call notification control unit 8 counts the call signal from the caller based on the detection result by the call detection unit 1.

Then, for example, the call signal is detected three times (step
204), the ringing notification controller 8 stops outputting the ringing tone (A) (step 205), and then the bell sound and the silent section are alternately successively alternated every 1 and 4 seconds, respectively. Output ringing tone (B) shown in FIG.
206).

At this time, the incoming call notification control unit 8 waits for a voice input so that the recognition operation of the voice recognition unit 4 is performed only in the silent section of the ringing tone (B) every four seconds (step 207).

Next, when a sound "high" is input from the microphone 3 in the silent section of the ringing tone (B), the sound recognition unit 4 judges the sound (step 208).

When the incoming call notification control unit 8 determines that the voice recognition unit 4 is “high”, it stops outputting the ringing tone (B) (step 209), and then outputs a switching signal to the changeover switch unit 7.

Then, the changeover switch unit 7 switches from the handset talking state to the hands-free talking state (step 210).

As described above, in the present embodiment, the voice recognition unit 4 operates only in the silent section of the ringing tone (B) every four seconds, thereby taking in only a specific voice and reliably performing voice recognition. This makes it easy and reliable to switch between a handset call and a hands-free call.

In this embodiment, the case where the silent section of the ringing tone (A) output from the incoming call notification control unit 8 is set to 4 seconds is not limited to this example. It may be shorter than 4 seconds or longer than 4 seconds.

When the incoming call notification control unit 8 detects the ringing signal three times, the output of the ringing sound (A) is stopped, and instead, the ringing sound (the bell sound and the silence section alternately and continuously every 1 and 4 seconds, respectively). The case where B) is output has been described. However, the present invention is not limited to this example, and the ringing tone (B) may be output after a certain period of time has elapsed after receiving a calling signal using a timer or the like.

Furthermore, the case of the unspecified speaker voice recognition system in which the voice recognition unit 4 performs a similarity calculation with a standard pattern registered in advance when recognizing a specific voice obtained via the speaker 3 has been described. However, the present invention is not limited to this example, and a specific speaker voice recognition method in which the voice of a specific caller is registered in advance may be applied.

Furthermore, the case where the voice command is switched to the hands-free call by setting the voice command to "high" has been described. However, the present invention is not limited to this example, and other functional units such as a voice synthesis output unit and an answering machine, and "wait" and "lus" When a "wait" command is input, the voice synthesis output unit outputs "Please wait" to the caller, or a "ruth" command is input. In such a case, the answering machine function may be operated.

[Effect of the Invention] As described above, according to the telephone of the present invention, since the voice recognition means can capture and recognize only the predetermined voice, erroneous recognition of the predetermined voice can be prevented. This makes it possible to easily and reliably switch between the handset call and the hands-free call.
